Hi Mike and all other gentoos ;) |
| 50 |
|
| 51 |
all of your mentioned options are enabled (since genkernel and me did |
| 52 |
it). |
| 53 |
|
| 54 |
i copied all data to another partition /dev/sdb9 and disabled initrd. by |
| 55 |
the way, i think that initrd was running, because all the scans after |
| 56 |
executing the initrd ran without problems. despite, i disabled it and |
| 57 |
got a kernel panic, like: |
| 58 |
|
| 59 |
""" |
| 60 |
[md] scanned 0 and added 0 |
| 61 |
... |
| 62 |
VFS: cannot open root device "sdb9" or unknown block(0,0) |
| 63 |
please append correct "root=" |
| 64 |
... |
| 65 |
Kernel panic - not syncing: VFS: unable to mount root fs on |
| 66 |
unknown-block(0,0) |
| 67 |
""" |
| 68 |
|
| 69 |
i don't know how to handel this error, since my grub entry is correct |
| 70 |
(or not?): |
| 71 |
|
| 72 |
""" |
